What is the correct order of medications that should be given to a patient with suspected STEMI?

• A. Oxygen - keep SpO2 >94%, Aspirin 324 mg PO, Nitroglycerin 0.4 mg SL; may repeat q5min x2, Pain medication if needed (Morphine/Fentanyl), Ondansetron/Metoclopramide/Prochlorperazine
• B. Oxygen; Nitroglycerin; Aspirin; Pain medication; Ondansetron
• C. Oxygen; Aspirin; Pain medication; Nitroglycerin; Antiemetic
• D. Oxygen; Aspirin; Nitroglycerin; Antiemetic; Pain medication

Answer: (A)

In suspected STEMI, start with oxygen if the patient is hypoxic to keep SpO2 above 94%, because adequate oxygen delivery helps myocardial tissue during ischemia. Next give aspirin 324 mg chewed to rapidly inhibit platelets and begin limiting thrombus propagation; the sooner antiplatelet therapy starts, the better the outcome. Giving nitroglycerin after aspirin preserves the antiplatelet effect while still providing vasodilation to relieve chest pain and reduce myocardial oxygen demand, as long as the patient has a stable blood pressure and no contraindications (such as hypotension or use of certain medications). If pain persists after nitro, administer pain relief with morphine or fentanyl to alleviate discomfort and reduce sympathetic drive, but do so carefully to avoid hypotension. Finally, provide an antiemetic such as ondansetron, metoclopramide, or prochlorperazine to prevent or treat nausea, which can accompany ACS treatments and IV opioids. This sequence aligns with prioritizing rapid antiplatelet action, prompt reperfusion-supporting therapy, and symptom control while watching hemodynamics.
